Help with Grumpy Mod

I got really tired of buying the Polaris paper filter so the dealer sold me the UNI - just clean and reuse he said - when I pulled it off after a couple of rides I had dust in the in take. Bummer.

UNI = no good.

So after some research I think the Grumpy mod is the solution for me.

Have many questions. Does anyone have a link to a pictorial guide on how to do it? I get the general idea but the devil is in the details.

Thanks
